After four years at the University of South Florida, Seabrook was selected in the 2009 draft by the Colorado Rapids. However, the Indiana native was not offered a contract and eventually signed with Crystal Palace Baltimore instead.

In 2011, Seabrook moved to the Harrisburg City Islanders. In 2012, the forward made his foray abroad in a brief stint with Enköping in the Swedish third division. Later that year, he earned a move to the Finnish top flight, signing with FC Haka.
